Every proposal faces the same invisible competitor: the decision to do nothing. The buyer already has a workaround, a tolerance for the problem, or a belief that they can solve it eventually without spending money. The cost-of-inaction page is the answer to that competitor. It doesn’t argue that your price is reasonable. It calculates what the status quo is already costing, in revenue, time, talent, or risk, and puts that number next to your fee. The comparison is the argument. You don’t need to make it explicitly.
The Gap Selling Foundation
Keenan’s Gap Selling framework establishes a principle that experienced salespeople and consultants know empirically: the buyer is not comparing your solution to the alternatives. They’re comparing your solution to staying where they are. The gap between the current state and the desired state is the problem. The size of that gap determines whether the buyer has enough urgency to act.
The cost-of-inaction page makes the gap visible in financial terms. It quantifies what it costs the buyer to live with the gap for one more month, one more quarter, or one more year. Once that number is on the page, your fee is evaluated in a completely different frame. A $15,000 engagement fee is a large number until it sits next to a calculation showing that the problem costs $22,000 per month in lost revenue. At that point, $15,000 is not a cost, it’s a month and a half of the problem, solved permanently.
The Cost-of-Inaction Formula
The calculation structure is straightforward. You need three inputs, all of which come from the discovery conversation.
Input 1: The current metric. What is underperforming right now? Conversion rate, churn rate, cost per lead, revenue per customer, hours spent on a process, anything measurable and relevant to your service. Get the actual number from the buyer during discovery. If they don’t know it, that itself is data.
Input 2: The performance gap. What should that metric be? Use your past client results, industry benchmarks, or a conservative estimate of what’s achievable. Be transparent about the source of the benchmark. “Based on three similar engagements, this metric typically improves from X to Y” is credible. “Industry data suggests this metric could reach Y” is weaker but still usable. “You should be at Y” with no evidence is not credible.
Input 3: The monthly financial impact. Translate the performance gap into monthly dollars. If conversion rate improves from 2% to 4% on 1,000 monthly leads at $3,200 average deal value, the monthly impact is 20 additional closes x $3,200 = $64,000. If hours per week on a manual process drop from 14 to 2 for a team of three at a $65/hour loaded rate, the monthly impact is 12 hours x 3 people x 4.3 weeks x $65 = $10,062.
The cost of inaction per month is the financial impact of the gap continuing unchanged. Multiply by the estimated months to solve independently (typically 6–18 for most business problems without external help) and you have the total cost of the status quo.
Three Worked Examples
Marketing consultant, B2B SaaS. Buyer converts 1.8% of trials to paid. Industry benchmark is 4%. Monthly trial volume: 800. Average first-year contract: $4,400. Gap: 2.2 percentage points. Monthly cost of gap: 17.6 additional customers per month x $4,400 = $77,440 in monthly revenue not captured. Engagement fee: $18,500. Comparison: the engagement pays for itself in less than one additional week of gap.
Operations consultant, professional services firm. Buyer’s project managers spend 11 hours per week on manual status reporting for a team of 6 at a $72/hour loaded rate. Benchmark after system implementation: 1.5 hours per week. Monthly time cost of gap: 9.5 hours x 6 people x 4.3 weeks x $72 = $17,636/month in recoverable capacity. Engagement fee: $11,200. Comparison: the engagement pays for itself in 19 days of recovered capacity.
HR consultant, growth-stage company. Buyer’s average time-to-hire for senior roles is 94 days. Benchmark after process restructure: 42 days. At three senior roles per quarter and a productivity ramp cost of $8,000 per hire for each week of delay, the quarterly cost of the gap is 7.4 weeks x 3 hires x $8,000 = $177,600 per year. Engagement fee: $22,000. The cost of one quarter of the status quo exceeds the engagement fee by a factor of eight.
The calculation doesn’t need to be precise to be persuasive. It needs to be credible and grounded in the buyer’s own numbers. A conservative calculation that the buyer can verify is more persuasive than an aggressive calculation they suspect is inflated.
What to Do When the Buyer Pushes Back on the Numbers
Invite them to adjust the inputs. “If you think the conversion improvement is more modest, say 0.8 percentage points rather than 2, the monthly revenue impact is still $25,600. At that rate, the engagement still pays for itself in the first month of improved conversion.” This response does two things: it demonstrates that your math is transparent and that the conclusion holds even at conservative assumptions.
Never defend the original number stubbornly. The point of the calculation is not to be exactly right, it’s to establish that the cost of inaction is significantly larger than the cost of acting. As long as that relationship holds at any reasonable input, the frame is intact.
Placement and Format
The cost-of-inaction page belongs immediately before the investment page. Half a page of content is sufficient: a two- or three-line setup, the calculation displayed clearly (not buried in a paragraph), and a single closing sentence that bridges to the investment. Keep the math visible, don’t translate it into prose where the numbers disappear.
The strongest frame for any investment conversation is not “here is what this costs.” It is “here is what not deciding costs.” The cost-of-inaction page builds that frame before the buyer reaches the price, so when they do, the comparison is already loaded in your favor.
